IWR1443: IWR1443 about the FFT questions

Part Number: IWR1443

Hi team,

The customer would like to use IWR1443.

Q1: He would like to know what  the function is for the FFT Hardware Accelerator. 

Q2: Is  the function for the FFT Hardware Accelerator correct as below: 

After the data is input, the FFT Hardware Accelerator can calculate the FFT and the customer does not need to design a software to calculate the FFT?

Q3: If the above function for the FFT Hardware Accelerator is correct, does IWR1443 have any restriction for the FFT ponts and any other aspect?

Q4: Can IWR1443 support the floating-point operations if the customer uses his design software to calculate the FFT?

Best Wishes,
